Synaptosomal Toxicity and Nucleophilic Targets of 4-Hydroxy-2-Nonenal
4-Hydroxy-2-nonenal (HNE) is an aldehyde by-product of lipid peroxidation that is presumed to play a primary role in certain neuropathogenic states (e.g., Alzheimer disease, spinal cord trauma). Although the molecular mechanism of neurotoxicity is unknown, proteomic analyses (e.g., tandem mass spectrometry) have demonstrated that this soft electrophile preferentially forms Michael-type adducts ...
متن کاملEffect of 4-Hydroxy-2-Nonenal Modification on -Synuclein Aggregation
Several observations have implicated oxidative stress and aggregation of the presynaptic protein-synuclein in the pathogenesis of PD.-Synuclein has been shown to have affinity for unsaturated fatty acids and membranes enriched in PUFAs, which are especially sensitive to oxidation under conditions of oxidative stress. One of the most important products of lipid oxidation is 4-hydroxynonenal (H...
متن کاملCytotoxicity and metabolism of 4 - hydroxy - 2 - nonenal and 2 - nonenal in H 202 - resistant cell lines
Toxic aldehydes, such as 4-hydroxy-2-nonenal (4HNE) and 2-nonenal (2NE), formed during lipid peroxidation have been isolated and implicated in the cytotoxic effects of oxidative stress. We have investigated the cytotoxicity and metabolism of 4HNE and 2NE in control (HA-1) cells and in two H202-resistant Chinese hamster fibroblast cell lines. The H202resistant cells were found to be significantl...
متن کاملModification of Cytochrome c by 4-hydroxy- 2-nonenal: evidence for histidine, lysine, and arginine-aldehyde adducts.
4-Hydroxy-2-nonenal (4HNE), a major secondary product of lipid peroxidation, has been associated with a number of disease states involving oxidative stress. Despite the recognized importance of post-translational modification of proteins by products such as 4HNE, little is known of the modification of cytochrome c by this reagent and its analysis by mass spectrometry. The purpose of this study ...
متن کاملCatalytic activities of Werner protein are affected by adduction with 4-hydroxy-2-nonenal
4-Hydroxy-2-nonenal (HNE) is a reactive α,β-unsaturated aldehyde generated during oxidative stress and subsequent peroxidation of polyunsaturated fatty acids. Here, Werner protein (WRN) was identified as a novel target for modification by HNE. Werner syndrome arises through mutations in the WRN gene that encodes the RecQ DNA helicase which is critical for maintaining genomic stability. This her...
